Answer:
The correct answer is - 1:1:1:1.
Explanation:
Mendel performed cross in between peas with round, green seeds (RRyy) with peas having wrinkled, yellow seeds (rrYY)
gametes : Ry and rY
↓
F1 : RrYy
Test cross is the cross between f1 offspring and recessive parent which is
gametes : RY, Ry, rY, ry and ry
↓
F2 : RrYy, Rryy, rrYy, and rryy.
So, the phenotypic ratio of the offspring would be - 1:1:1:1.
Answer:
this cell could be in the process of mitosis, specifically metaphase.
Different life forms adapt to their environment. Stable ecosystem creates a stable environment for life forms. In stable environment, life forms do not have to adapt all the time and their energy can be invested into other life processes, such as growth, reproduction, etc. Stability of ecosystem is important for adjoining ecosystems because that way boundaries and influences could be extended. Stable ecosystems are able to interact and both benefit from each other.
Answer: <em>Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. Closer to the horizon, the sky fades to a lighter blue or white.

Rr and rr in the ratio of 1:1
Explanation:
If allele for smooth seed is Dominant over the allele for wrinkled seeds, and they are crossed 50 per-cent of the progeny will be heterozygous dominant and 50 per-cent will be homozygous recessive.
Rr X rr
Rr Rr rr rr F1 generation.
r r
R rR rr
r Rr rr
From Punnet square it will be 50 per-cent chance each of rr and Rr.
